Dear all Su2 users;

I have run serial Su2 successfully, but in parallel setting,each time a new error and I am really confused!

I have installed Parallel version for windows 7 as Setup-Windows_x64-MPICH2.exe, MPICH2 64 bit, Python 2.6.6 64 bit and and Numpy-1.7.1 x64 for Python 2.6.6.

From this point what else do I have to do to configure parallel runs?
What is that SU2_RUN environment variable setting? Please say in details. I really need your help.


Thanks a lot.

Hi Mike,

Here is a procedure on how to install and run SU2 in parallel. Please look the attached zip file.

Let me know if it helps you.

Thanks,
Yonatan

very nice one,thanks yona.

I followed this on 2.0.5, need to change mpirun to mpiexec in su2_py\su2\run\interface.py.

dear Yonatan;

Thanks a lot for your complete and useful note. I have followed as you mentioned, but now there is a new error :

Do you have any idea???

Thank you.

Hi Mike,

Did you check the MPICH2 syntax in parallel_computation.py python script ? The executable file name of MPICH2 should be the same in the python script.

As an example, if the MPICH2 executable file name is msiexec, then you have to use this in the python script as follows: run_SU2_DDC = "mpirun -np 1 %s" % (run_SU2_DDC)
(change mpirun –np to msiexec -n)



Or could you upload your configuration file and the python script so that I can try in my PC.

Thanks
Yonatan

Hi dear Yonatan;

My MPICH2 executable is mpiexec.exe and I have already done that change in python parallel script. Here are my *.cfg and parallel_computation.py files. Since the size of mesh_ONERAM6_turb_hexa.su2 mesh file is high, I have not sent it. It is in test case folder of SU2 under "rans" folder.

Thanks again for your kinds.

Mike

Hi Mike,

Looking to your config file, I just found out that the Navier-Stokes wall boundary marker (MARKER_NS) was not defined properly. In addition to that the MARKER_HEATFLUX= ( WING, 0.0 ), is not a recognizable tag by SU2. So after I delete "MARKER_HEATFLUX= ( WING, 0.0 )" andreplace by
MARKER_NS=( WING ), it works.

You can find the config file in the zip folder.

Let me know if it works.

Thanks
Yonatan

Thanks a lot Yonatan. I am going to try it. But the cfg file was for SU2 tutorial files and supposed to be true!!!! Any way I will inform you. Again Thanks for your quick answer.

Best Regards

[fluidmechanics]

Thanks Yonatan. It works. You are one of the bests. I will send you a private message. Thanks my friend.

Hello Yona,

I followed the guide you provided, however, I can seem to find the SU2_RUN file which you added an environment variable for. That seems to be the only step I'm unable to complete. I get this error:

C:\Users\spl4ckd>python D:\Programs\SU2_Para\SU2\SU2_PY\parallel_computati on.py -f turb_ONERAM6.cfg -p 4
Traceback (most recent call last):
File "D:\Programs\SU2_Para\SU2\SU2_PY\parallel_computat ion.py", line 36, in <module>
sys.path.append(os.environ['SU2_RUN'])
File "C:\Python34\lib\os.py", line 635, in __getitem__
raise KeyError(key) from None
KeyError: 'SU2_RUN'

Could you direct where exactly SU2_RUN is so that I can create an environment variable for it?

Thank you,
Jared

Hi Jared,

have you followed already the steps outlined here: https://github.com/su2code/SU2/wiki/...s-Installation ?
